"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post

"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe

"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark

"Excellent datafeed !!!" - Comment from Arely

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn

"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

"I cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles

"Its working FABULOUSLY for me!! Holy cow...there has been so much I've been missing lately, and with this feed and Linnsoft software...I'm in the game now." - Comment from Chris R.
